Abstract: Some embodiments are directed to a surgical robotic system including a suspension structure 1, a carriage 2 arranged to be mounted to the suspension structure, and a manipulator arm 3 arranged to be detachably docked to the carriage via a docking mechanism. The docking mechanism includes a first docking connector on the manipulator arm and a second docking connector on the carriage. The first and the second docking connector may establish an electrical connection between the manipulator arm and the carriage when the manipulator arm is docked. The manipulator arm includes a connector for connecting the manipulator arm via a cable to an electric power supply, and be configured to supply the carriage with the electrical power via the electrical connection when the manipulator arm is docked.

Abstract: Some embodiments are directed to a robotic manipulator interface for coupling a hinged surgical tool to a manipulator of a surgical robot, the interface including a first interface member to be coupled to the manipulator, and a second interface member to be coupled to the first interface member, the second interface member being arranged to mount the hinged surgical tool, wherein the first interface member includes a pinching mechanism for pinching the hinged surgical tool when the second interface member is coupled to the first interface member, wherein the pinching mechanism includes two movable protrusions protruding from a surface of the first interface member, the first interface member including a built-in actuating mechanism for moving the protrusions to each other to push two arms of the mounted hinged surgical tool towards each other so as to actuate the mounted hinged surgical tool through the sterile drape.
